Reciclagem da Acrilonitrila butadieno estireno para aplicação em filamento de impressora 3D

Abstract

This work aims to demonstrate the feasibility of recycling polymers, specifically ABS copolymer, as a solution to reduce environmental impacts caused by incorrect disposal of plastic waste. Recycling these materials has the potential to create an environmentally friendly source of filaments for 3D printers, which are widely used in the manufacture of customized products, especially in assistive technologies. The results indicated that the thermal and mechanical characterization of recycled materials is essential to understand their behavior. The thermodynamic-mechanical analyzes revealed that recycled ABS presents well-defined glass transitions, similar to those of virgin ABS, as observed in the literature. The research used the CRM (Characterization and Recycling Management) tool to evaluate and optimize the recycling process, generating essential technical-scientific information for decision-making on the use of recycled materials. The study highlights that the use of recycled ABS in 3D printers is viable, offering a sustainable alternative that maintains the quality of the final product. The application of the CRM tool proved to be crucial for identifying intersection points that allow the optimization of the properties of recycled materials, extending their useful life and promoting standardized recycling methods. The results reinforce the importance of recycling for sustainability, demonstrating that recycled polymeric materials can compete in quality with virgin materials, benefiting both the industry and the environment.
